Why Adding Attic Insulation is a Smart Idea

Living in Alberta means we all depend on natural gas and coal for our energy prices, and year after year, those prices go up. Increased prices for utilities means less money in our bank accounts. Exact numbers vary from house to house, but about 40 percent of our utility bills are from heating our homes. Since Edmonton winters are extremely long and cold, making improvements to your home’s attic insulation can save you a lot of money.

At Crest Roofing, we can add insulation to your home. It’s the simplest, most cost effective way to lower your energy bills during the colder months. In this article, we’ll tell you all about attic insulation and what you can expect if you increase your roof’s R-value.

Why Should I Have Insulation Added to My Attic?

You might notice that your house gets pretty cold during the winter and you feel the need to crank up the heat or pile on sweaters. During summer months, your house might get too hot to handle, making you want to camp outside. Extreme temperature fluctuations are a sign that your house is poorly insulated and is a big motivator for homeowners who want consistent, comfortable temperatures.

Even if your house doesn’t experience temperature extremes, adding attic insulation is a smart idea. It can lower your heating bills by 10 to 50 percent! And that’s not all! There are many more benefits:

  • Your roof will last longer
  • Well insulated roofs are less likely to develop ice dams
  • It will help reduce your carbon footprint
  • There are environmentally friendly insulation materials available
  • The insulation material we usually use will protect your attic from fire, mold, fungus, and pests

It’s Not Just Adding Insulation. We Seal Leaks and Do Roof Repairs Too!

Sometimes, increasing insulation in your attic isn’t as simple as just adding some fill. To help you get your home perfectly insulated we will remove your old insulation if it has a low R-value and replace it with the good stuff. Things like wood chips and rotten insulation don’t help your roof at all.

We also check your roof’s condition. If there are leaks or rot anywhere, we will fix it. You could have all the insulation in the world, but if cold air is getting in, your house is still going to be cold and drafty.

We also make sure your roof and attic are fully sealed. We seal any windows, we seal around pipes, ducts and wires, and we seal around chimneys and flues so that cold air doesn’t get in and warm air doesn’t get out.

One exception is your soffit vents, which are essential for your roof’s ventilation (Read more about roof ventilation here. We make sure your soffit vents are left clear because your attic needs to have proper air flow. Keeping your roof cool will help prevent ice dams.

The Materials we Use for Attic Insulation

There are a few common types of attic insulation that we find in homes:

  • Wood chips
  • Cellulose
  • Fibreglass

Wood chips aren’t an ideal material to use for insulation. Hugh Cairns explains it well on his article about wood chip insulation “If you compare the R-Value of sawdust and wood chips to our modern insulation products, the insulation value is poor. Often, the depth of the wood shaving insulation was insufficient – to today’s standards, and as it settled, it has little or no thermal benefits.”

Cellulose is another type of insulation we see in attics. There are a few reasons why it’s not the best material for attic insulation, but here are the main two:

For one, it’s heavier than fibreglass insulation. This really matters in your attic, because you don’t want to have a lot of weight on your ceilings. Too much weight can lead to sagging and premature aging of your support structures.

Second, cellulose is highly flammable. It has to be treated with fire-retardant chemicals to meet minimum safety requirements. Those chemicals don’t stay on the cellulose, making it more and more flammable as time goes on.

Fibreglass insulation is made of glass, which is inherently non-flammable. There is no need for fire-retardant chemicals.

We use fibreglass insulation, particularly Owens Corning AttiCat, and we’ve had great results with it.
